Application filed Apri127,

old to provide a tally-stripmechanism for the purpose of supporting and feeding a tally-strip or record strip of paper so that so. i strip extends around the platen of the machine to receive carbon impressions of certain of the data writ-ten upon the worksheets.

In the tan-fold type of machines havingarotary platen the platen is-mounted in its 'riage so that it can be swung up intopo on where the course of the web is tightened sufiiciently to enable the car hon sheets to be shifted toa new position I with respect to the web. This isdone after each form has been written upon and pre paratory to the writing of the next form.

A feature of the present invention is the provision of means and the arrangement and location of parts for supporting and guiding a. tally-strip (and its associated carbon strip, it such. is used) so as to per nit the swinging of the platen to carbonshittinp; position.

Another feature of this invention is the provision of means and arrangements; and ocation of parts whereby the reachesof the tally-strip (and its associated carbon strip) that extend to and from the platen are substantially taut in the normal and-carbon shitting positions of the platen around which said strip is looped. so as not to intert'ere with the operation oi"? the machine or to be interfered with by the machine in operation. i

Preferably both the receiving roll and the supply rolloft the tally-strip are mounted directly on the carriage, where they do not become disconnected from the line-spacing n'iechanism during the upward displacement of the platen frame. These spools occupy positions above the work-webs when they straightened out so not to form in typewritin r machines, generally, it is .rrrnwnrrrne MACHINE.

In the Underwood fan-told? typewriting machine such as is shown in the patent to Smith 1,177,54i6..the rotary platen 10 is mounted to rotate in platen swinging frame 11. which in turn is pivotally mount ed on a, front rodli supported by the platen .carria e Being so mountedthe platen swinging framefill may he moved by hand from the tulhlined position shown in Fig. 4, to the dot and dash line position shown in said'figure.

The tan-told or separate work-webs, if such are used, are guided over a supplementary carriage frame 14h which. is suitably supported and connected to the typewriter carriage 13 at 15 to travel therewith in letter feed direction. The carriage frame .14 1S provided with means 16 for holding superposed carbon sheets between the folds of the "folded web or the separate webs. The workwebsand carbon sheets. are thence ledover the paper table 17., carried by the typewriter .carriage 13, and down around the platen 10 toprinting position. A paper table. 18' is provided on the. swinging frame at the delivery side of the platen for supporting the delivered work sheets and for other purposes. After ator1n-" has been written. the

platen frame 11 is swung upwardly and for v Wardly about its pivot 12 to straighten the course of the: web, to permit the carbon In the course of typewritinptheplaten is;

moved in line-space direction by the usual pawl 18 and ratchet it to which the platen is connected by means of a gear" similar to ratchet, an idle pinion similar to the gear 21 secured. to the platen shaft 22, to which the platen is also secured. The usual detent 23, engages the ratchet l8, and bolt the ratchet in line space position. The usual feed rolls ill and 25, co operate with the platen to feed the work sheets witli rotation thereof. b v l Y I It will be noted that in the tan-told typewriting; machines the platen 10 has a considerable extent of movement to and from normal position on the typewriter carriag;e; I p i r The tally-strip mechanism of the present invention may in some details. ei'nbody teatu-res that'are shown in the patent to Hart l 28Ll60. it comprises a supply roll 26, and a receiving roll 2'1 secured .i'espectiuely to shatts28- an 129, which are journaledin brackets30?,SeCured to the side of the Cl riage 13; and thus both. thesupply spool G :and' the receiving. spool 27 may be mounted independently of the swinging; ill which carriesthe platen around tally-strip is. looped. i

- The tally-strip 30, and its associated carbon-sheet strip it such isusedare tier around the platen l0 line-byline, by the ro tation of the receiving spool 27, which roe line space mechanism provided upon the car-- I riage and not shitting with the platenswinginn 2 frame. The illustrated means for doing this (TODlPlflSGS a ratchet ll. fixed to the shaft 29 ot the receiving: spool and a pawl 32 to engage the ratchet u 'lii eel and move the same by an arm 5-33 "piirotally mounted on a shaft 29" p The arm 33 carryingthe pawl 32 is ronnected by a link to the slide 2501: the usual line-space mecha nism which carried the pawl (18%]?01 the platenratcl'iet'lS A suitableisprinn" inaintains the pawl 32 inengagement -with the ratchet wheel 55 that, when the line-space slide moves ,rearwa rdly to rotate theplaten, the link swings. the arm 33 suhiciently to cause the pawl 32 to? rotate the shaft 29 and w id tally-strip 30 and its carbon on the rec spool 27 and thus feed the tally-sti able distance to space the items rne'reon.

,Any suitable feeding mechanism the tally-strip may be'eniployed withoutdepart" ring; from the spirit ot intentii feeding mechanism described and ilthe gear 19 and which is secured to the that there will be a slack in the tree stints,

tween the latter'and the paper-table on strip lead to the pl tation may be causedhy the operation oi The arrangement is such,

present time it being understood t 2-5, as shown in Fig. :2, and thus nia be lineted independently of the rotation of the platen, it desired. I In order to permit the platen to be moved to carbon shitting position without interior- 'ence from or undue tensioning ot' the tall strip, 1 preferably mount the tally 1p supply roll 26 in such a position on the carr 36. of sutlicient extent to permit the platen to move backwardly and then forwardly during the platen-displa(ring operations in the loop ot the tally strip. lhe rolls can be so positioned thatthe. slack will be produced by the platen itself. in moving away from normal position, the supply and receiving rolls be ng mounted, as shown in the drawings, upwardly and rearwardly, ot the ilaten, and-this position of the rolls may be described as being above the path oi. the straightenedout work-webs and belo-uithe paper-table on the swinging frame b the carriage. 1

)i' course, it is not essentialto the present intention th t the rolls 2G an iZIbe mo nted int iisparticulai. position, although in '-1 cases it is preferable, because it is sut it the tally strip he guided to said in from strip-controlling rolls which mounted elsewhere. It is desirable oten troni this point its equivalent and r n troni the platen to suln-ftautiallj the same point i' the rereii'i' mean tor the ip is to be z uouuted on the carri-a frame. I t the receivin means is to be mounted on the platen frame itis not essential where the part oi the telly st ip at the del" iry side oi? the platen leads to.

l i here supply and rec 37 rolls are proand returns to substantially the san'iepoint therefore, I have provided a guide whose function is to engage the stretch oi the Web between the platen and the supply roll. 26 and brin 'partot' lllle fill'l'lfi into close 171'0XiI11lty"With the receiving roll. 'lhere are other ways-o1 doing this, but the spe rangeinent shown the one 1 pr such close proximity that the strip star -s it c 1y intention in its broader aspect includes any suitable means for bringing about the same result. 'Y I "Itwill be not-ed that at the lower end of the paper table 18, there is preferably pro- ,vided a rounded-guide 37 which engages the stretch 36 of the tally strip between the platen and the receiving roll 27. This guide serves to reduce the friction and to facilitate the passage of the strip under the table 18,-but has in addition another "function and that is to provide normally a slight bend or tensioning 38 in the strip so that immediately the platen is moved. from normal position a slight slack will be provided in the strip. The paper table may moveatf a greater speed than the rotation of the platen aused during the shifting by its planetary movement around the gear which connects it to the line space wheel, the latter being held against movement by the detent. Thishas the eiiect of preventing the platen from feeding the strip off the supply roll during the planetary movement. The same is true when the platen is just about in writing position on being returned, the slight slack being maintained until the very last portion of the movement when the guide 37 causes the strip to be taut.

In operation, when the platen is to be shifted. to carbon retracting position the guide 37 may permit a slight slack, then the platenmoves rearwardly and upwardly through the loop formed by the tally-strip then, on reaching its extreme rearward position, the platen moves forwardly to J its position otrest when it'again may cause the loop to be substantially taut. in this taut position the tally-stripwill not interfere with the movement of the web or webs while the latter are beingadjusted and or 39 rotatably mountedupon rod 40 suitably supported by the carriage.

The supply roll 26 may be provided with Friction device 4-1 whereby the strip is held against accidental movement. q

Variationmay be resorted to within the scope out my invention and portions of the improvements may be used without others.
